If the digit of 0 is allowed, then:

1/(10*9*8)= 1/720

If it is not permitted, then:

1/(9*8*7)= 1/504

I hope this helps you!

Answer:

The probability that you will get a 3-digit combination correct is:

   1/720

Step-by-step explanation:

We are asked to find the probability that you will get a 3-digit combination correct if no digits in the combination can be repeated.

Now the favorable number of outcomes=1 (which is the correct combination)

Total number of outcomes=  10×9×8

(first place has 10 choices of digits from 0-9 ,second has 9 choices excluding the one at first place and third place has 8 choice)

                                           =720

Probability= number of favorable outcomes/total number of outcomes

                 =  1/720

(x-5)1/2+5=2<br> (x-5)1/2=-3<br> [(x-5)^1/2]^2=(-3)^2
Studentka2010 [4]

Answer:

x = 14

Step-by-step explanation:

You want to solve for x, right?

(x-5)^(1/2)+5=2

You have it right so far.

(x - 5)^(1/2) = -3

(x - 5)  =  (-3)^2

x - 5 = 9

x = 9 + 5 = 14

What value of x will make the triangles similar by the sss similarity theorem? 15.9 59 77 96.8
deff fn [24]

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

<h3>What is SSS similarity theorem?</h3>

The SSS similarity theorem is the theorem which is used to check the two triangle are similar or not.

SSS means the side-side-side. This theorem states that if all the three sides of a triangle are proportional to the three corresponding sides of the another triangle, then the triangles are similar.

In the given image, the sides of the first triangle are 35,20 and 20. The sides of the second triangle are x, 44,44.

Thus, by the SSS similarity theorem,

\dfrac{x}{35}=\dfrac{44}{20}\\x=\dfrac{44\times35}{20}\\x=77

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.
